VEGETABLE OIL AND FAT REFINEMENT APPARATUS Russian patent published in 2015 - IPC C11B3/00 

FIELD: food industry.

SUBSTANCE: apparatus for refinement of vegetable oils and fats consists of a vertical cylindrical body with a conic bottom enclosed inside a steam jacket, a vertical shaft with rectangular vertical blades, a drive, nipples for delivery and discharge of oil, heating steam and condensate as well as the gas phase; the rectangular vertical blades are perforated with slanted flat-topped guides installed on their rear sides for each hole respectively.

EFFECT: invention allows to improve efficiency of vegetable oil stirring with reagent drops or bleaching powder particles which reduces the duration of chemosorption and absorption processes; stirring energy expenditure is also reduced due to creation of predominantly mixed radiaxial and tangential circulation of the liquid phase in the apparatus with reduction of front resistance of the vertical rectangular blades as conditioned by their perforation and the slanted flat-topped guides in place.
